SPEQIFIGATION forming part of Letters Patent N 0. 791,154, dated May 30, 1905. Original application filed April 29, 1904, Serial No. 205,446. Divided and this application filed October 5,1904. $erial No. 227,184.

To aZZ whom it may concern: I

Be it known that I, HARRY P. MACDONALD, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Book-Shelves, of which the following is a specification.

The object of this present invention is to provide a book-shelf which will be extremely cheap to manufacture, in which the parts are easily assembled, and in which the arrangement of the several parts with respect to each other is such that a very strong and light shelf may be formed which will be capable of successfully withstanding the weight of the books placed thereon.

The present a plioation is a division of an application file by me on the 29th day of April, 1904, entitled Improvement in bookshelves, its serial number being 205,446.

In the accompanying drawings, Figure 1 is a top plan view of a portion of the shelf. Fig. 2 is an end view. Fig. 3 is a transverse section taken at a distance from one of the transverse bars. Fig. 4 is a transverse section at one of the transverse bars. Fig. 5 is a side view. Fig. 6 is a longitudinal section. Fig. 7 is a partial top plan View of a blank from which the ion itudinal bar is formed, and Fig. 8 is a partial top plan view of the blank from which the transverse bar is formed.

The blank from which the transverse bar is formed is so shaped that when the bar is completed it will have two vertical portions 1 and 2, connected along their upper edges,

the vertical portion 2 having a plurality of u wardly-projeoted ton nos 3 cut therein. The blank from which t e longitudinal bar is formed is so shaped that when the bar is completed it will have a horizontal portion 4, flaps 5, projected therefrom, downwardlyextended sides 6 7, upwardly-folded lips 8 9, and locking-flaps 10 11, projected from the sides 6 and 7. These flaps are partially severed from the sides by slits 12 13.

When the shelf is set up, the end flaps 5 are folded downwardly over the outer face of the transverse bar and thence upwardly a short distance on its inner face. The side are there folded toward each other between the vertical portions 1 and 2. The bases of the tongues 3 are interlocked with the ends of the longitudinal bars, as the notches 12 13 permit the longitudinal bars to be depressed until portions of the ends of their sides abut against the vertical portion 2 of the transverse bar.

The vertical portion 1 of the transverse bar may be provided with a tongue 14, fitted to be folded along the outer side of the outermost longitudinal bar and secured thereto by rivets 15 or other suitable fastening devices.

What I claim is 1. A book-shelf comprising transverse bars and longitudinal bars, each transverse bar having inner and outer vertical portions connected along their upper edges, the inner vertical portion having a plurality of upwardly-projected tongues out therein.

' 2. A book-shelf comprising transverse bars and longitudinal bars, the transverse bars having inner and outervertical portions, 7 5 the inner vertical portions having upwardlyprojected tongues out therein and tongues at the ends of the outer vertical portions folded alon the outer sides of the outermost longitudina bars and secured there to.

3. A book-shelf comprising transverse bars and longitudinal bars, the transverse bars having inner and outer vertical portions and tongues cut in the inner vertical portions, the longitudinal bars having downwardly-extended sides provided with flaps at their ends folded between the tongues and the outer vertical portions of the said transverse bars.

4. Abook-shelf comprising transverse bars and longitudinal bars, the transverse bars having inner and outer vertical portions and tongues cut in the inner vertical portions, the longitudinal bars having horizontal portions, downwardly-extended sides, 5 side flaps folded between the tongues and the outer vertical portions of the transverse bars and flaps at the ends of the horizontal portions folded downwardly along the outer sides of the said transverse bars.

5. A bookshelf comprising transverse the said transverse bars and upwardly on bars and longitudinal bars, the transverse the inner sides thereof. bars having inner and outer vertical portions In testimony that I claim the foregoing as and tongues out in the inner vertical pornyinventionlhave signed 1nyna1ne,in pres- 5 tions, the longitudinal bars having horizontal enoe of two witnesses, this 4th day of ()cto- I 5 portions, downwardly-extended sides, side ber, 1904.
